Abstract: A communication device (10) can include a transceiver (12), a transducer or microphone (14) coupled to the transceiver for receiving voice input from a user, and a processor (16) coupled to the transceiver. The processor can be programmed to receive (32) a predetermined type of phone call or an indication of a caller indication from a calling party and warp (38) a voice input from the user of the communication device based on the caller indication. How the predetermined type of phone call is determined can be done in a number of ways including using an optional caller identification module (18). The caller ID module can provide information on whether the caller is recognized or whether the caller ID information is unavailable.

Abstract: A method and apparatus to correct a periodic signal, such as a frequency reference, based upon another frequency reference. A lower accuracy frequency signal generator (104) provides an uncorrected frequency reference signal (122) to a frequency corrector (106). Frequency corrector (106) counts cycles of a frequency reference signal (124), as generated by a higher accuracy reference generator (102) for a time period derived from the uncorrected frequency signal. Based upon the cycles counted, pulses are added or removed from the uncorrected frequency signal (122) to produce a corrected frequency signal (126). A ratio of pulses to be removed from the uncorrected frequency signal (122) is determined from the number of cycles counted and a counter arrangement is provided to automatically remove the required ratio of pulses from the uncorrected frequency signal (122).

Abstract: A portable communication device (10) includes a transceiver (12 and 14), an acceleration sensor (20) coupled to the transceiver, and a processor (16) coupled to the acceleration sensor. The processor is programmed to monitor (32) an acceleration profile of the portable communication device and compare (48 and 52) the acceleration profile of the portable communication device with at least one pre-stored acceleration profile (18).
